Bevy & Rust Star Wars Scene - How it Works

BEVY and RUST + Star Wars = epic. This is a code breakdown / walk through of this project I built in 1 hour using Bevy and Rust.
Everything from laser shooting walkers + xwing to procedual world generation to heightmap rendering shader.

after trying my hand at bevy shaders and failing horribly I definitely got a whole new kind of appreciation for what you managed to do in a single hour

[ym-xxkj]

Oh wow, you're really full-sending Bevy. A friend of mine and I decided to pick it up too after seeing your videos, since we thought it might be fun to create a small RPG-adventure with it.

I'm beginning to love zig more than Rust but I still love you the same amount Tantan!

2:56 I gotta nitpick this, but that code does not make the lasers 6 times faster every second. At 1 FPS, it makes them 7 times faster every second. At 2 FPS, it makes them 16 times faster every second. At 5 FPS, it makes them 51.5 times faster every second. At 10 FPS, it makes them 109.95 times faster every second. At 60 FPS, it makes them 304.48 times faster every second.

The way you actually make it 6 times faster every second is `laser.velocity *= Also, when something is accelerating, `translation += velocity * time` is also wrong; the object will travel different distances depending on framerate. The correct formula depends on how the object is accelerating, but in this case it's `translation += (velocity_after - velocity_before) / 6.0f64.ln();`. I don't like delta time game loops because it's really hard to get consistent behavior across a range of framerates.

error[E0277]: the trait bound `LandscapeMaterial: Asset` is not satisfied :((

Time to steal your idea for the lasers to add colliders into my scene lol.

[RADkate]

oh cool this is basically advanced shader art

[adampaul]

Is there any documentation anywhere to how to recuperate your landscape material in the shader ? Why is there #(uniform[0]) ... why is there @group(1) @binding(0) ? I am really struggling using this.

[SuboptimalEng]

I just started learning WebGPU with TypeScript and realized that I missed out on so much (especially the compute shaders).

My issue with gltf was, that even simple models did not work, and I had no 3d experience. So I am hyped about next bevy release, which I hope will support those pesky ..._1 values some models use for UV lighting or animations.

I am getting an error. What should I do? :((

Hello, thanks for your videos, is it possible to buil an html 5 webgl game with Bevy at the moment?

[NielsGx]

is the game that stuttery or it's the recording ?

[steve]

tantan, man where ya been? Have you been working at a different job?

[SpikerStudios]

Quickly, someone get acerola to do a video on Rust shaders

Thanks for this nice tutorial! It just run slow on my AMD Ryzen 7 5800h notebook :( (Ubuntu 22.04 linux)
